Honey pots are used to attract computer attacks to a virtual operating system that is a virtual instantiation of a typical deployed operational system. Honey nets are a collection of these virtual systems assembled to create a virtual network. The subject system uses a forward deployed honey net combined with a parallel monitoring system collecting data into and from the honey net, leveraging the controlled environment to identify malicious behavior and new attacks. This honey net / monitoring pair is placed ahead of the real deployed operational network and the data it uncovers is used to reconfigure network protective devices in real time to prevent zero-day based attacks from entering the real network. The forward network protection system analyzes the data gathered by the honey pots and generates signatures and new rules for protection that are coupled to both advanced perimeter network security devices and to the real network itself so that these devices can be reconfigured with threat data and new rules to prevent infected packets from entering the real network and from propagating to other machines. Note the subject system applies to both zero-day exploit-based worms and also manual attacks conducted by an individual who is leveraging novel attack methods.

Techniques may automatically detect bots or botnets running in a computer or other digital device by detecting command and control communications, called “call-backs,” from malicious code that has previously gained entry into the digital device.

In some embodiments, the invention involves protecting network communications in a virtualized platform. An embodiment of the present invention is a system and method relating to protecting network communication flow using packet encoding / certification and the network stack. One embodiment uses a specialized engine or driver in the network stack to encode packets before being sent to physical network controller.

Otherwise, the packet is dropped. An embodiment of the present invention utilizes virtualization architecture to implement the network communication paths. Other embodiments are described and claimed.

A method of implementing a firewall that receives a layer of policies from each of multiple entities with different levels of authority.

Embodiments of the invention enable minimum latency site independent real-time video transport over packet switched networks. Some examples of real-time video transport are video conferencing and real-time or live video streaming. In one embodiment of the invention, a network node transmits live or real-tine audio and video signals, encapsulated as Internet Protocol (IP) data packets, to one or more nodes on the Internet or other IP network. One embodiment of the invention enables a user to move to different nodes or move nodes to different locations thereby providing site independence. Site independence is achieved by measuring and accounting for the jitter and delay between a transmitter and receiver based on the particular path between the transmitter and receiver independent of site location. The transmitter inserts timestamps and sequence numbers into packets and then transmits them. A receiver uses these timestamps to recover the transmitter's clock. The receiver stores the packets in a buffer that orders them by sequence number. The packets stay in the buffer for a fixed latency to compensate for possible network jitter and / or packet reordering. The combination of timestamp packet-processing, remote clock recovery and synchronization, fixed-latency receiver buffering, and error correction mechanisms help to preserve the quality of the received video, despite the significant network impairments generally encountered throughout the Internet and wireless networks.

Aggregating physical connections from customers for presentation to an access router and de-aggregating traffic from a shared link(s) from the access router. Ports of an aggregation unit may be configured such that each has a unique identifier in the place of information (e.g., the layer 2 address) originally in the layer 2 header. The layer 2 (e.g., MAC) address of the customer device connected with the port can be associated with, and therefore determined from, the IP address of the attached device. When a packet is received from a customer, information in the layer 2 header is changed to a unique identifier assigned to a logical port or interface associated with the physical port. When a packet is received from the access router, it is placed on the port assigned to the logical port associated with the destination layer 2 address (or associated with other bits of the unique bit string and at least some of those bits are replaced with the destination layer 2 address of the device associated with the port.

A data processing system implements a security protocol based on processing data in packets. The data processing system comprises processing packets for storing filter code and processing data packets according to stored filter code, and a policy managing function for generating filter code and communicating generated filter code for packet processing. The packet processing function is arranged to examine, whether the stored filter code is applicable for processing a certain packet. If the stored filter code is not applicable for the processing of a packet, the packet is communicated to the policy managing function, which generates filter code applicable for the processing of the packet and communicates the generated filter code for packet processing.

In one embodiment, the present invention is a method and apparatus for DNS pre-fetching for multiple clients. In one embodiment, all packets coming into or going out of a local network are scanned for application protocol, domain names, and / or other information. If pre-defined criteria indicate that the network is interested in a particular domain name, a DNS lookup is performed and the corresponding IP address is cached by the local DNS server. The local DNS server is thereby able to quickly respond to future requests for the cached domain name. Moreover, because the IP address is cached at the local DNS server, any client connected to the local DNS server on the local network can request the cached domain name from the local DNS server and be quickly connected to the indicated domain name.
